9EHWA DIAMOND INDUSTRIAL TOOLS

INNOVATOR IN TECHNOLOGYSINCE 1975

Forming diamond dressers are used for dressing specific forms

into conventional abrasive wheels requiring longer tool life.

Natural diamonds have very high resistance while they could be

easily broken and have unsteady tool life. On the other hand, syn-

thetic diamonds have steady tool life. Generally, the bigger radius

of diamonds can ensure longer tool life. However, the much bigger

radius can get grinding wheels to be burned because it makes the

grinding wheels grit blunt.

Recommended angle and radius (For chisel dresser )

Rough grinding : R 0.3~0.5, 50 ~ 60

Finish grinding : R 0.1~0.25 , 30 ~ 45

Two or more selected diamonds are set in a metal matrix to provide multi dia-

mond points for dressing larger and wider conventional abrasive wheels.

Multi-point diamond dressers have two types. One is a general type for dress-

ing straight type conventional abrasive wheels; the other a blade type for

dressing larger and conventional abrasive profile wheels at lower cost.

Multi-point diamond dressers using diamonds made by chemical vapor depo-

sition are suited to get high quality surface finish and consistent performance.

On the other hand, multi-point diamond dressers made of elongated natural

diamonds, which is called Fliesen tool, have longer tool life.

Burnishing tools

Burnishing tools are manufactured by natural or mono crystalline diamonds. The burnishing process is a cold

process using proper pressure without removal of the work pieces. The burnishing tools are very useful for

metalworking because they help get high quality mirror-like surface finish and meet dimensions as

requested. The diamond burnishing tools can ensure longer tool life and good surface finish.

PCD (Poly-crystalline diamond) dressers

PCD dressers are cost-effective alternative in dressing conventional abrasive profile wheels. The PCD is easier

to get desired shapes than the other diamond materials. As a result, PCD dressers can dress grinding wheels

with complex profiles. The relatively lower tool life can be compensated by lower price.

Contact gauges

Contact gauges with natural diamonds or poly-crystalline diamonds have almost 100 times longer tool life than

tungsten carbides or high-speed steel. The diamond contact gauges can ensure highly accurate measurement

with ultra wear resistance.
